ARTIFICIAL BUlLDlNG-STONE.

SPEGIFTCATION forming part of Letters Patent No. 437,525, dated September 30, 1890. Application filed March 29, 1890- Serial N01 345,879. (No specimens.)

To all whom it may concern.-

Be it known that I, ARNOLD voN SOLE MACHER-ANTWEILER, chamberlain and lord of manor of Schloss Wachendorf, near Satz- 5 vey, in the Kingdom of Prussia and German Empire, have invented a new and useful 1m proved Method of Producing W'eather-Proof Artificial Enamel Stones Indifferent Against Acids, of which the following is a specification.

[O This invention has reference to a new or improved manufacture of artistic enamel bricks and plates or tiles weather-proof, acid-proof, not penetrable by moisture, and of so highly durable a nature as to be practically indestructible. They are intended for usein building operations, whether to serve in lieu of ordinary facing-bricks, the same size as which they can be made, or to be employed alternately or in conjunction with ordinary facingbricks-for example, in the adornment of facades. They are also intended to serve in the form of plates or tiles for covering Walls in all cases where dryness, cleanliness, and

elegance are desired, for which purposes it has been usual to employ known kinds of glazed clay plates or tiles of the less valuable or costly descriptions. My bricks, plates, or tiles are also speciallysuitable for use in the construction of friezes, floors, &c. They are opaque and can be produced as a pure white enamel, and also in all colors or shades of color and marbled, and with various patterns, designs, and emblems.

The enamel is made of a mixture of the 5 following substances in or about the proportions stated, namely: one hundred parts, by weight, of silicic acid; five parts, by weight, of fiuor-spar; five parts, by weight, of feldspar; twenty parts, by weight, of soda; five parts, by weight, of tin-ash; five parts, by weight, of alum-earth; five parts, by weight, of red lead; two and one-half parts, by weight, of talc, and two and one-half parts, by weight, of cryolite. This mixture is melted in aregenerof from about 1,500 to 2,000 in such a manative glass-melting furnace at a temperature that a number of intercommunicating or connected spaces are produced, which as the bricks, plates, or tiles are built up or secured in place become filled with mortar or cement, thereby insuring a firm attachmentof the bricks, plates, or tiles to the wall or floor or surface to which they are applied. The designs, ornaments, emblems, monograms, &c., on the upper or front faces are obtained by pressure in the molds by means of dies or parts adapted to produce the patterns or designs required.

The bricks, plates, or tiles can be produced with a polish or luster or with a dull surface.

What I claim, and desire to secure by Letters Patent of the United States, is 7 A method of manufacturing water-proof artificial enamel stones indifferent against acids by melting a mixture of the following substances: one hundred parts, by weight, of silicic acid; five parts, by Weight, of 'fiuor- 8o spar; five parts, by weight, of feldspar; twenty parts, by weight, of soda; five parts, by Weight, of tin-ash; five parts, by weight, of alumearth; five parts, by weight, of red lead; two and one-half parts, by weight, of talc; two and one-half parts, by weight, of cryolite, in a regenerative glass-melting furnace at a temperature of from about 1,500 to 2,000 and castingthe resulting fluid mass, with eventual addition of suitable coloring agents, in molds 0 into the form of bricks or plates or tiles of the desired shape and size with projecting border and interrupted transverse ribs or pro jections at the back.

In witness whereof I have hereunto set my 5 hand in presence of two Witnesses.
